About MediaWiki
MediaWiki is free and open source wiki software written in PHP. It is the collaboration and documentation platform that runs Wikipedia and the other Wikimedia projects, used by hundreds of millions of people each month to collect and organize knowledge.
Pages are written in wikitext and organized with namespaces, categories, and reusable templates. Editing is collaborative, with full revision history behind every page, plus search and a programmatic API for accessing content.
The software is extensible both on-wiki and through hundreds of extensions, and it is localized in over 350 languages. It scales from small private wikis to sites the size of Wikipedia, and is developed through global collaboration under the Wikimedia Foundation.
